Tips: Silicon Carbide (SiC) is produced in an electric furnace at temperatures in excess of 2200 Celsius. SiC is produced by fusing coke and high purity silica sand. The result is the formation of SiC crystals which are very hard. SiC also has a very high thermal conductivity and is very strong at elevated temperatures.
Mohs hardness is 9.2.,
Vickers hardness is 3000-3300 kg/mm,
microhardness is 3000-3300kg/mm3.
Density generally viewed is 3.20g/ mm3
density of heap is 1.2-1.6g/ mm3
specific gravity is 3.20~3.25
Among abrasives, silicon carbide’s hardness is higher than corundum, and ranked below diamond, CBN and boron carbide.
Silicon Carbide can used widely in Metallurgy Industry/ Nonmetal foundry/ Fireproof industry and grinding material industry as its Heat- Resistance corrosion resistance abrasion resistance.
